Have you ever wondered why people are persuaded by outright lies during political campaigns? And why lies tend to "stick" even after they're debunked by facts? Some new research sheds light on why this happens, at least in terms of people's thought processes, if not their underlying emotional drives.
A study led by Stephan Lewandowsky of the University of Western Australia explains part of what may happen. The researchers found that "Weighing the plausibility and the source of a message is cognitively more difficult than simply accepting that the message is true -- it requires additional motivational and cognitive resources."
